Your documents never leave your browser.

The core promise of this site: the markdown you write or paste is processed entirely in your browser. Your document content is never transmitted to, stored on, or logged by our servers.

• Local storage — documents are auto-saved to your browser's localStorage so your work survives a reload. This data lives only on your device; clearing browser storage removes it.
• Share links — when you create a share URL, your document is compressed and encoded into the link itself. We do not store a copy; recipients decode it locally. Read the technical explanation of how private share links work.
• Rendering API — if you use the "copy rendered HTML" feature or the public /api/render endpoint, the submitted markdown is converted in memory and immediately discarded, never logged or retained.

We do not require accounts and do not collect personal profiles. To understand aggregate usage we rely on:

• Google Analytics — anonymized usage data (pages visited, approximate location, device and browser type) collected via cookies. See Google's Privacy Policy or opt out with the GA Opt-out Add-on.
• Plausible Analytics — a privacy-friendly, cookieless service that records aggregate page views without tracking individuals across sites.

Analytics never see the content of your markdown documents.

The site is supported by advertising. Ad networks we work with (currently Adsterra, potentially Google AdSense in the future) may use cookies or similar technologies to serve and measure ads, including interest-based ads. These third parties have their own privacy policies. You can limit interest-based advertising via your browser settings or opt-out pages such as aboutads.info.

The editor itself sets no cookies — preferences like dark mode live in localStorage. Cookies may be set by the third-party analytics and advertising services described above. You can block or delete cookies in your browser; the editor keeps working normally.

The site is a general-audience developer tool and is not directed at children under 13. We do not knowingly collect personal information from children.

Because your documents never leave your device, the primary security boundary is your own browser. The site is served over HTTPS, and rendered output is sanitized with DOMPurify to protect against cross-site scripting.

We may update this policy from time to time. Changes will be posted on this page with an updated date; continued use of the site constitutes acceptance of the revised policy.
